Katy Perry's Prismatic Tour: 6 things to know about the pop star's current show

Katy Perry's current tour is dubbed Prismatic for good reason: by all accounts, it showcases a bright, broad color spectrum. If it doesn't cover all of ROY G BIV, it may be deemed a violation of truth-in-advertising law.

The ubiquitous pop singer has a reputation for her pageants of eye candy by all definitions of the phrase - remember her peppermint-swirl and gumball-machine garb of previous tours? The mammoth 10-month jaunt launched in May and goes deep into 2015, with two Michigan dates: She'll make her Grand Rapids debut at Van Andel Arena (after canceling two 2011 shows due to illness) Aug. 10, and will stop at The Palace of Auburn Hills the following night.

Perry's new show is, as expected, studded with multiple multi-platinum hits, including breakthrough tracks "I Kissed a Girl" and "California Gurls," her biggest U.S. hit "Firework" and recent smash singles "Roar" and "Dark Horse." The singer hasn't altered her aesthetic, which marries sex-symbol suggestiveness with the wide-eyed innocence that appeals to younger audiences. Here are six things you need to know to catch up with Perry and the Prismatic Tour:

• Coinciding with the tour launch, Perry was featured on the cover of Rolling Stone, the interview featuring several juicy news bites about the possibility of single parenthood (“I don't need a dude... It's 2014! We are living in the future; we don't need anything. I don't think I'll have to, but we'll see. I'm not anti-men. I love men. But there is an option if someone doesn't present himself,” she said), how conspiracy theorists find Illuminati or witchcraft symbols in her show (“It sounds crazy. Weird people on the internet that have nothing to do find, like, strange triangles in your hand motions. I guess you’ve made it when they think you’re in the Illuminati") and accusations of cultural appropriation in her stage show (“It came from an honest place. If there was any inkling of anything bad, then it wouldn't be there, because I'm very sensitive to people").

• Alongside the Rolling Stone piece, Perry's new video for "This Is How We Do" debuted, the song getting its own over-the-top clip after being featured in the singer's Covergirl cosmetics ad earlier this year. The video features backup dancers in Pee-wee Herman garb, dancing ice creams a la old movie-theater concession-stand promos and the type of nutso color palette that likely required many rainbows be murdered. Perry also wears a one-piece bathing suit boasting a cheese-and-pepperoni pizza design; read into that however you want.

• What the critics think matters less in the wake of praise from the President of the United States, though. One of the key dates on the tour was at the White House Aug. 1, when Perry performed her hit "Roar" at a reception honoring the 46th anniversary of the Special Olympics, and President Obama called her "a wonderful person" and "one of my favorite people." It's not the first time Perry has supported for the President, having performed at rallies during his 2012 re-election campaign.

• Opener Kacey Musgraves is no stranger to the touring circuit – since the release of her major-label debut “Same Trailer Different Park” in March, 2013, she has performed Michigan dates as opener for Kenny Chesney and Lady Antebellum. She’s known for her 2012 platinum-selling, Grammy-winning country hit “Merry Go ’Round” as well as charting singles “Follow Your Arrow” and “Keep It to Yourself.” Forbes’ recent piece on the singer found the connection between Musgraves and Perry, proclaiming “Follow Your Arrow” “the descendent of Perry’s ‘I Kissed A Girl’ - albeit a slightly more hedged exhortation for a much more conservative audience.”

• The second opening act, Ferras, is a recent signee to Perry’s Metamorphosis label imprint, via Capitol Records. His new self-titled EP was released in June, and features the single “Speak in Tongues”; his other single, 2008’s “Hollywood’s Not America,” was featured on the seventh season of “American Idol.”
